Urination

Urination, also known as micturition, voiding, tinkling, peeing, weeing, pissing, and more rarely, emiction, is the ejection of urine from the urinary bladder through the urethra to the outside of the body. In healthy humans the process of urination is under voluntary control. In infants, some elderly individuals, and those with neurological injury, urination may occur as an involuntary reflex. In other animals, in addition to expelling waste material, urination can mark territory or express submissiveness. Physiologically, micturition involves coordination between the central, autonomic, and somatic nervous systems. Brain centers that regulate urination include the pontine micturition center, periaqueductal gray, and the cerebral cortex. In male placental mammals, urine is ejected through the penis. In female placental mammals, urine is ejected through the vulva.
